What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity (p = mv).

Front

How do you calculate momentum?

Back

Momentum (p) = mass (m) × velocity (v).

Front

If a 1 kg ball moves at 100 m/s to the left, how fast does a 100 kg girl move to the right to conserve momentum?

Back

1 m/s to the right.

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

What is the formula for calculating velocity?

Back

Velocity (v) = distance (d) / time (t).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the unit of momentum?

Back

The unit of momentum is kg·m/s.

Front

What does it mean if an object has a greater momentum?

Back

It means the object has either a greater mass, greater velocity, or both.

Front

What is the relationship between force and momentum?

Back

Force is the rate of change of momentum (F = dp/dt).
